Charlie Sheen is set to get a taste of his own "Torpedoes of Truth" at his Comedy Central Roast on Saturday.

It was announced this week that William Shatner, former "Saturday Night Live" performer Jon Lovitz and "Private Practice" star Kate Walsh have been added to the show, which will be taped on September 10.

Also added to the bill were comedians Patrice O'Neal and Amy Schumer and guitarist Slash. The previously announced names include "Jackass" star Steve-O and Mike Tyson, while "Family Guy" creator Seth MacFarlane will perform as the roast master.

The "Roast of Charlie Sheen" special will air on September 19 at 10 p.m. ET - an hour after the CBS sitcom "Two and a Half Men" returns for its ninth season without the actor. Ashton Kutcher joins the show but his role has not yet been announced. The sitcom is set to air that day between 9 and 9:30 p.m. ET.

Sheen, 45, has been one of the most talked about - and joked-about - celebrities in recent months, mainly due to his on-air rants and catchphrases made before and after his firing from "Two and a Half Men" in March as well as his partying lifestyle (check out some of his best quotes).

"You could say I've been providing kindling for this Roast for a while," Sheen said in a Comedy Central statement obtained by OnTheRedCarpet.com. "It's time to light it up. It's going to be epic."

Sheen was axed from "Two and a Half Man" after he insulted its co-creator Chuck Lorre in on-air interviews and following months of turmoil, which included a stint in rehab to treat alcohol and drug abuse, reports of wild nights with former adult film stars, and legal battles with his then-wife.

After he was axed from the comedy series, which reportedly paid him more than $1 million an episode, Sheen went on an on-air rampage, slamming show executives and coining catchphrases such as "Duh, winning!" in television interviews and via his own Webcast, dubbed "Torpedoes of Truth." He then launched a "Torpedo of Truth" comedy tour.

For several shows, Sheen was joined by Jeffrey Ross, a familiar face on Comedy Central Roast specials, and allowed the comedian to joke about him on stage.
